10: .SH DESCRIPTION
11: .I Gnuplot
12: is a command-driven interactive function plotting program.
13: .PP
14: If files are given,
15: .I gnuplot
16: loads each file with the
17: .I load
18: command, in the order specified.
19: .I Gnuplot
20: exits after the last file is processed.
21: .PP
22: Here are some of its features:
23: .PP
24: Plots any number of functions, built up of C operators, C library
25: functions, and some things C doesn't have like **, sgn(), etc. Also
26: support for plotting data files, to compare actual
27: data to theoretical curves.
28: .PP
29: User-defined X and Y ranges (optional auto-ranging), smart axes scaling,
30: smart tic marks.
31: .PP
32: Labelling of X and Y axes.
33: .PP
34: User-defined constants and functions.
35: .PP
36: Support through a generalized graphics driver for

77: The PC version compiled by Borland C++
78: supports IBM CGA, EGA, MCGA, VGA, Hercules and ATT 6300 graphics.
79: Other devices can be added simply, but will require recompiling.

82: .PP
83: Load and save capability.
84: .PP
85: Output redirection.
86: .PP
87: All computations performed in the complex domain. Just the real part is
88: plotted by default, but functions like imag() and abs() and arg() are
89: available to override this.
90: .SH X11 OPTIONS
91: .I Gnuplot
92: provides the \fIx11\fP terminal type for use
93: with X servers. This terminal type is set automatically at startup if
94: the \fBDISPLAY\fR environment variable is set, if the \fBTERM\fR environment
95: variable is set to \fBxterm\fR, or if the \fB\-display\fR command line
96: option is used.
97: For terminal type \fIx11\fR, \fIgnuplot\fP
98: accepts the standard X Toolkit options and resources such as geometry, font,
99: and background. See the X(1) man page for a description of
100: the options.
101: In addition to the X Toolkit options:
102: .PP
103: \fB\-clear\fP requests that the window be cleared momentarily before a
104: new plot is displayed.
105: .PP
106: \fB\-gray\fP requests grayscale rendering on grayscale or color displays.
107: (Grayscale displays receive monochrome rendering by default.)
108: .PP
109: \fB\-mono\fP forces monochrome rendering on color displays.
110: .PP
111: \fB\-persist\fP lets plot windows survive after main gnuplot program exits.
112: .PP
113: \fB-raise\fP raises the plot window after each plot.
114: .PP
115: \fB-noraise\fp does not raise the plot window after each plot.
116: .PP
117: \fB\-tvtwm\fP requests that geometry specifications
118: for position of the window be made relative to the currently displayed
119: portion of the virtual root.
120: .PP
121: These options may also be controlled with resources in your \fB.Xdefaults\fR
122: file.
123: For example: \fBgnuplot*gray: on\fP .
124: .PP
125: \fIGnuplot\fP provides a command line option (\fB\-pointsize \fIv\fR) and
126: a resource (\fBgnuplot*pointsize: \fIv\fR) to control the size of points
127: plotted with the "points" plotting style. The value \fIv\fR is a real
128: number (greater than 0 and less than or equal to ten) used as a
129: scaling factor for point sizes. For example, \fB\-pointsize 2\fR uses
130: points twice the default size, and \fB\-pointsize 0.5\fR uses points
131: half the normal size.
132: .PP
133: For monochrome displays, \fIgnuplot\fR does not honor foreground or
134: background colors. The default is black-on-white. \fB\-rv\fP or
135: \fBgnuplot*reverseVideo: on\fP requests white-on-black.
136: .PP
137: For color displays \fIgnuplot\fP honors
138: the following resources (shown here with default values). The values
139: may be color names in the X11 rgb.txt file on your system, hexadecimal
140: RGB color specifications (see X11 documentation), or a color name
141: followed by a comma and an \fIintensity\fR value from 0 to 1. For example,
142: \fBblue,.5\fR means a half intensity blue.

198: \fIGnuplot\fP honors the following resources for setting the width in
199: pixels of plot lines (shown here with default values.) 0 or 1 means
200: a minimal width line of 1 pixel width. A value of 2 or 3 may
201: improve the appearance of some plots.

225: \fIGnuplot\fP honors the following resources for setting the dash style
226: used for plotting lines. 0 means a solid line. A 2 digit number \fIjk\fR
227: (\fIj\fP and \fIk\fP are >= 1 and <= 9) means a dashed line with a
228: repeated pattern of \fIj\fR pixels on followed by \fIk\fR pixels off.
229: For example, '16' is a "dotted" line with 1 pixel on followed by 6 pixels
230: off. More elaborate on/off patterns can be specified with a 4 digit value.
231: For example, '4441' is 4 on, 4 off, 4 on, 1 off. The default values shown
232: below are for monochrome displays or monochrome rendering on color or
233: grayscale displays. For color displays, the defaults for all are 0
234: (solid line) except for \fBaxisDashes\fR which defaults to a '16' dotted
235: line.
